9th Class Math Ex 5.1 Q4 (iv) Solved | Class 9th Math New Book Exercise 5.1 | 9th Math 2025 Ex 5.1

Описание: Welcome to this complete and easy-to-understand lecture on Exercise 5.1 Question 4 from Class 9 Mathematics (Unit 5: Linear Equations and Inequalities) according to the New Punjab Textbook 2025 syllabus.

In this video, you will learn how to indicate the solution region of given linear inequalities by shading on the xy-plane, using clear and neat steps.

In this lesson, we cover all inequalities from (i) to (vi):

2x – 3y ≤ 6

2x + 3y ≤ 12

x + y ≥ 5

4x – 3y ≤ 12

3x + 7y ≥ 21

y ≤ 4 and more!


You will learn:
✅ How to convert inequalities into boundary lines
✅ Solid vs dashed boundary lines
✅ How to select a test point
✅ How to draw and shade the exact solution region
✅ How to handle multiple inequalities in the same graph

This video is ideal for Class 9 students who want to master graphical representation of inequalities with proper shading.
